Problem: it is taking me five minutes to open a model from the mart that takes ~ 30 seconds to open offline. This model has around 1,000 tables in it.
Solution: the customer increased their java memory on the mart server and now their models open from the mart within a minute.
Open regedit and go to this location: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\MartServer\Parameters\Java
